- SATISFYING FLOW FROM FAUCET – From the first drop! Hydrovos’ Mini-Tank for Tankless RO systems effectively provides high quality drinking water during the time delay all tankless RO systems have built in as a safety feature. Tankless RO’s need to ensure feed supply is adequate to protect pump and other components from running dry.
- SOLVES PROBLEMS WITH REFRIGERATOR ICE MAKERS – Today’s advanced ice machines and water dispensers on board refrigerators are equipped with protective devices that ensure the valves don’t open if there is insufficient water supply. Tankless ROs can struggle to provide adequate flow, especially when they first turn on. Hydrovos Mini-tank will overcome this protection by supplying sufficient water to ensure the pressure sensors are satisfied.
- UNIVERSAL FIT – Hydrovos’ Mini-Tank for Tankless RO systems can be used with any tankless RO system with a 1/4" product water delivery line. This is the line that runs up to the separate faucet mounted to the sink top.
- INSTALL KIT INCLUDED – Includes fittings that will fit the most commonly used product water line, 1/4" polyethylene. 1/4” Stem Tee Adaptor fits into the Ball Valve that connects to the top of the tank. Complete installation takes less than 5 minutes.
- MINI-TANK PRECHARGE – Hydrovos Mini-Tank for Tankless RO Water Filter Systems arrives ready to use. The air charge is optimized for best use with a tankless reverse osmosis system.
